Notes about the recipes, with conversions for other measurements:
American cooks use standard containers, the 8-ounce cup and a tablespoon that is the equivalent of 3 teaspoons. 16 level tablespoons fill a cup. Obviously a packed cup of butter will weigh more than one of flour. Please weigh ingredients when the recipe calls for weight measurements. They will be much more accurate than cup measurements.
